- Make a number of implicit expectations explicit:
- Every patch must compile.
- All CI tests must pass.

- Mention that the patch author is expected to add reviewers and explain
how to choose them.

- Explain the patch submission rules in terms of Gerrit labels.

Also do some cosmetic changes, like adding empty lines, shuffling some
paragraphs around.

Add support for hexadecimal and pointer format specifiers to snprintf()

The current implementation of snprintf() does not support pointer and
hexadecimal format specifiers, which can be needed, for instance, for
DTB manipulations.

This patch adds that functionality by borrowing some code from the
printf() implementation.

qti: Add SPMI PMIC arbitrator driver

This patch adds a very rudimentary driver for the SPMI arbitrator used
to access the PMIC. It doesn't support all the controller's actual
arbitration features, so it should probably not be used concurrently
with a running kernel (and it's also not optimized for performance). But
it can be used to set a few registers during boot or on shutdown to
control reset handling, which is all we need it for.

The patch adding platform support for sc7180 landed around roughly the
same time as the patch that changed GICV3_IMPL to GICV3_SUPPORT_GIC600.
Thus the sc7180 Makefile is still using the old variable name which now
no longer does anything, and it hangs on boot due to the lacking GIC-600
support. This patch fixes the issue.

driver, to check that the boot configuration settings are
intact. Usually, this function should be called at the
end of the boot cycle.

This function only calls panic() on silicon platforms.
